Wired ESD Strap (Acceptable)
Wireless ESD Strap (Unacceptable)
Furthermore, simply touching the chassis before handling parts is no longer allowed because this method does not ensure adequate ESD protection on parts with
increased sensitivity to ESD damage.
Chassis "Bare metal" Grounding (Unacceptable)
Handle all static±sensitive components in a static±safe area. If possible, use anti±static floor pads and workbench pads.
When handling static±sensitive components, grab them by the sides, not the top. Avoid touching pins and circuit boards.
When unpacking a static±sensitive component from its shipping carton, do not remove the component from the anti±static packing material until you are ready to install
the component. Before unwrapping the anti±static packaging, be sure to discharge static electricity from your body.
Before transporting a static±sensitive component, place it in an anti±static container or packaging.
Insulator Elements
It is critical to keep ESD sensitive devices away from internal parts which are insulators and are often highly charged. These are elements such as plastic heat sink casings.
DIMM lying on an insulator part (plastic heat sink shroud) ± Unacceptable
DIMM kept separate from the insulator part ± Acceptable
Transporting Sensitive Components
When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti±static bags for safe transport.
ESD Protection Summary
It is strongly suggested that all field service engineers use the traditional "wired" ESD grounding wrist strap and protective anti±static mat at all times when servicing Dell
products. In addition, it is critical that the engineer keep sensitive parts separate from all "insulator" parts while performing service and use anti±static bags for transport of
sensitive components.
